Structure of Proteins - Tertiary & Quaternary Structure

  • The tertiary structure of a protein is its unique three-dimensional structure. 
  • It occurs due to the following interactions:

                          -Hydrophobic Interactions
                          -Van Der Waals Interactions
                          -Disulfide Bridges
                          -H-bonds and Ionic Bonds

  • Some proteins are formed from several polypeptides, also known as subunits, and the interaction of these subunits forms the quaternary structure.
  • For example, Hemoglobin protein has two α and two β polypeptides together with four heme groups.
  • Weak interactions between the subunits help to stabilize the overall structure.
